Abstract
The utility model discloses a repeatedly usable's bleeder, including main part and install the swivel nut in the main part, the shape of main part is cylindric, and the inside of main part sets up right plunger, is connected for dismantling between plunger and the main part, and specific connection realizes through elasticity ball valve structure. The problem of current bleeder pound to have no progeny at the pin and to reinstallate the restoration is solved.
Description
Technical field
This utility model belongs to petroleum industry DP technology technical field, relates to a kind of reusable let out
Oil device.
Background technology
At present, during oil well overhaul, the oil column in oil pipe, bleeder Main Function exactly upper carry oil pipe it
Before, between oil pipe and sleeve pipe, set up a passage, make the You Heshui in oil pipe not with oil pipe together on carry,
Let out in well, to reach not pollute well head, the purpose of convenient working.
Modal be also simplest be exactly hammering oil discharger, when playing pump, drop-in tool (take out by general throwing
Beam hanger pipe nipple) pound bypass pin (hollow bolt), play the effect of connection oil jacket, such lift pipe string
The when of shackle, the oil in tubing string would not flow to well head, reduces and pollutes.But bleeder is the most not after Zhuan Jiing
Can re-use, say, that be disposable.So use cost is the highest, is let out by solution
The oil reusable problem of device, reduces cost and puts into, reduce the cost of individual well operation.
Utility model content
The purpose of this utility model is to provide a kind of reusable bleeder, solves existing bleeder
The problem needing to reinstall reparation of having no progeny is pounded at pin.
This utility model be employed technical scheme comprise that, a kind of reusable bleeder, including main body
And the swivel nut being arranged in main body, being shaped as of main body is cylindric, and the inside of main body arranges right plunger, post
For removably connecting between plug and main body, concrete connection is to be realized by elastic ball valve structure.
Of the present utility model it is further characterized in that,
Elastic ball valve structure includes spring and is placed in the steel ball on spring top, and spring is arranged at steel ball valve opening
In, steel ball can be pressed in steel ball valve opening by the elastic force of spring.
The plunger outer surface near oil pipe one end is peripherally disposed ring-type groove, the width of groove
Adapt with the size of steel ball.
Swivel nut is arranged on the outside of main body by screw thread, plays the effect of sealed steel ball valve opening, swivel nut interior
It is provided with sealing ring A between side and main body, plays the effect of sealing.
Sealing ring B it is provided with inside main body and between plunger.
Plunger is sealed the inside such as main body by base, and base is fixed with main body by interior swivel nut, base
Outside is provided with a protection set.
The beneficial effects of the utility model are,
Well solve current bleeder to need when lift pipe string to pound shortcoming that is disconnected, that open drain path,
After this novel bleeder is opened, the most reusable, mustn't repair.
Accompanying drawing explanation
Fig. 1 is the design drawing of this bleeder.
In figure, 1. main body, 2. swivel nut, 3. steel ball, 4 springs, 5. sealing ring A, 6 sealing ring B, 7
Plunger, swivel nut in 8,9 protection sets, 10. base, 11. steel ball valve openings, 12. grooves.
Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
A kind of reusable bleeder of this utility model, as it is shown in figure 1, include main body 1 and install
Swivel nut 2 on the body 1, being shaped as of main body 1 is cylindric, and the inside of main body 1 arranges right plunger 7,
For removably connecting between plunger 7 and main body 1, concrete connection is to be realized by elastic ball valve structure,
Elastic ball valve structure includes spring and is placed in the steel ball 3 on spring top, and spring is arranged at steel ball valve opening
In 11, steel ball 3 can be pressed in steel ball valve opening 11 by the elastic force of spring, and plunger 7 is near oil pipe
The outer surface of one end is peripherally disposed ring-type groove 12, the width of groove 12 and steel ball 3
Size adapts.
Swivel nut 2 is arranged on the outside of main body 1 by screw thread, plays the effect of sealed steel ball valve opening 11,
It is provided with sealing ring A5 between inner side and the main body 1 of swivel nut 2, plays the effect of sealing.In main body 1
Sealing ring B6 it is provided with between side and plunger 7.
Plunger 7 is by base 10 by the envelope such as inside of main body 1, and base 10 is by interior swivel nut 8 and main body
1 fixes.The outside of base 10 is provided with a protection set 9.
Bleeder of the present utility model is being used when, and when being put in main body 1 by plunger 7, one opens
Beginning steel ball 3 is pressed in steel ball valve opening 11 due to the effect of pressure, and when the groove 12 on plunger is with main
The position of the steel ball valve opening 11 on body 1 is to time upper, and steel ball 3 will move to the outside of steel ball valve opening,
Thus be stuck in groove 12, thus reach to be fixed on plunger 7 effect within main body 1, then when
When needing to take out plunger 7, by the active force certain to plunger so that steel ball abjection groove after with
I.e. it is pressed in steel ball valve opening 11, thus smoothly plunger 7 is extracted out.
The beneficial effects of the utility model are, compared with existing structure, inside adds spring assembly, when
Tripping out tubing string, when needing to open drain path, pound from top into instrument, elastic ball valve device is opened, and lets out
Oil passage is opened, liquid in tubing string flows out tubing string and arrives in well, it is to avoid oil water mixture pollutes well site,
Achieve bleeder and be excused from a college course the most reusable purpose.
